It may be fun to toss this popped deliciousness in the air and watch your best friend try to catch it but beware. The high levels of fat and sodium can lead to dehydration.


Avocados are a super-food so what could be so harmful about these? Well, the skin contains a toxin called persin that can be dangerous to animals. If they chew on the whole avocado, skin and all, they could experience respiratory distress, congestion, fluid accumulation around the heart, and even death.

Macadamia Nuts

These nuts can cause vomiting, the loss of control of body movements, weakness and depression. Most dogs do recover without any specific treatment therefore if your pup accidentally eats a macadamia nut, a full recovery is expected.


Grapes are one of the most toxic to dogs. They are among the worst for dogs as dangerous foods go.  This surprises many people. They can cause kidney failure and even death.

Onions and Garlic

Any members of the Allium plant family are toxic to dogs in any form, whether fresh, cooked, dried, or even garlic powder and onion powder. They can damage red blood cells, decrease oxygen flow, and can also lead to anemia, which may cause organ damage.

Tomato Plants

The red ripe tomato is not the dangerous part for dogs. It’s the, unripe tomato or the leafy green part of the plant (including stems), that will cause havoc. Unripened tomatoes and tomato plants contain a toxin called solanine that can cause gastrointestinal distress, lethargy, weakness, and confusion.

Coffee and Tea

Besides chocolate, caffeine is one of the most dangerous foods for dogs. It is a powerful stimulant, and according to the ASPCA, it can cause “vomiting, diarrhea, increased thirst, restlessness and an increased heart rate” in pets. If you think your pet has ingested coffee, tea, or an energy drink, get to the vet right away.


Dairy can be detrimental for your dog. I know cheese is a popular dog training treat, and we also sometimes wrap pills in it to get them to ingest their medicine. Even though it’s not one of the most dangerous foods for dogs, too much cheese can cause constipation or diarrhea.

Sugar-Free Gum

Xylitol is a naturally-occurring substance used as an alternative sweetener is most sugar-free gums and candies. But it’s really dangerous for dogs. Xylitol ingestion causes life-threatening low blood sugar. Be extra, extra careful about where you leave your gum and double-check labels of sugar-free foods for this sweetener.


It’s very important to know what you dog can and cannot have to eat. Some food is safe for your pet, such as lean meats, carrot sticks, and many fruits and veggies. It’s okay to treat your dog with a snack of your food on occasion but steer clear of the stuff mentioned in the list above. And as always, consult with your veterinary if you have additional questions.
